Interpretive Structural Model

PurposeClimate change and global warming pose a serious threat to the community as deglaciating environments trigger glacial lake outburst floods (GLOFs). The Sendai framework underpins the role of disaster risk reduction (DRR) for sustainable development, thereby calling for the development of GLOF hazard and risk assessment procedures. This study aims to delineate the enablers of GLOF risk and establish a contextual relationship between them.Design/methodology/approachThe risk enablers are identified from the extant GLOF literature, and the experts from disaster management area are consulted to explore the underlying contextual relationship among them. An interpretive structural model is developed from the responses to analyze the contextual relationships among the risk enablers.FindingsThe interpretive structural modeling results manifest that seismic activity, temperature and precipitation events, and proximity are key drivers that trigger flash floods from the lakes and an effective assessment of these triggers may contribute significantly to GLOF risk mitigation.Originality/valueThe study models the complex relationship among the risk enablers for a glacial flood hazard that find commonality across all geographic contexts. The findings provide the practitioners of DRR useful insights into these factors and their subsequent impact on others, while conducting hazard assessment of glacial lakes that may contribute to the sustainable development of settlements lying downstream to glacial lakes.

Os territórios de riscos de desastres são considerados, por diversos especialistas, resultados da associação entre exposição aos perigos naturais do ambiente, condições de vulnerabilidade social e entre as vulnerabilidades intrínsecas à Gestão de Riscos de Desastres. Tais territórios podem e estão sendo objetos de estudo de pesquisadores de diferentes áreas do conhecimento, inclusive da Geografia. O presente trabalho tem como objetivo caracterizar a exposição de comunidades do município de Alagoa Nova - PB aos riscos de movimentos de massa e alagamento. A metodologia está dividida em duas etapas, as quais possuem, em comum, os seguintes procedimentos: levantamento bibliográfico, levantamento de dados secundários, elaboração cartográfica, atividades de campo e diálogo com representante da Defesa Civil Municipal. Coloca-se como relevante à medida que os seus resultados conseguem apontar os fatores que devem ser priorizados pela Defesa Civil Municipal e por outras secretarias municipais para uma efetiva mitigação dos riscos nas comunidades. Diagnostic of Exposure to Risks of Mass Movement and Flooding in Communities of the Municipality of Alagoa Nova, Paraíba / BrazilA B S T R A C TDisaster risk territories are considered by various experts to be the result of the association between exposure to natural environmental hazards, conditions of social vulnerability, and intrinsic vulnerabilities to Disaster Risk Management. These territories can and are being studied by researchers from different areas of knowledge, including geography. The present work aims to characterize the exposure of communities in the municipality of Alagoa Nova - PB to the risks of mass movements and flooding. The methodology is divided into two stages, which have in common the following procedures: bibliographic research, secondary data collection, cartographic elaboration, field activities and dialogue with the Municipal Civil Defense representative. The work is considered relevant because its results can point out the factors that must be prioritized by the Municipal Civil Defense and other municipal secretariats for an effective risk mitigation in the communities.Keywords: Exposure factors; Risk; Disaster; Management

Post Disaster

Infrastructures are connected between themselves and their connections form a complex network. Disaster impacted infrastructures have a reduced level of serviceability. The impact of the reduction of serviceability of disaster-affected infrastructures cascades through the entire infrastructure network. The recovery capacity of the network governs the recovery curve of a disaster-impacted infrastructure network system. Moreover, the speed of recovery of the infrastructure network from a post-disaster condition to the pre-disaster condition dictates the resilience of the system. Building these capacities requires spending money. The extent of resilience that can be afforded under a given budget situation is termed as the feasible resilience. This paper presents a framework for planning the capacities so that the feasible resilience of the network can be maximized under a budget situation. To achieve the said objective, the recovery time of a disaster-affected infrastructure network has been minimized. The outcome is the optimal restorative capacities the network needs to have so that the feasible resilience is maximized under a specified budget condition. The outcomes can be used by the decision-makers in natural disaster risk mitigation planning.

Inundation Map

Flood hazard mapping is an effective non-structural measure for sustainable urban planning, protecting human properties, lives, and disaster risk reduction. In this study, flood hazard assessment for the Bago river basin was performed. The flood inundation map of the Bago river basin was developed by coupling a hydrological and hydraulic model with geographical information systems. Flood hazard maps with different return periods were developed. The flood hazard map can be utilized to enhance the effectiveness of disaster risk management activities.
